carb 7029223
I understand this 7029223 carb is for a 69 C10 with manual transmission and that is what's in my truck now. I want to replace it with a rebuilt carb, but I have an AT truck. Question is what #s are for a 69 AT 350 Chevy truck C10? Oh.. any leads on where to buy one. Thanks. Will

You'll want 7029224.
Gotta ask! What tranny you got? |

looks like I do have a modulator and also can based it on the shape of the pan. So go with 7029224? What would be the difference between the 223 and 224? Here's a pic of my carb now as it sits on the engine. |

Re: carb 7029223
Most factory TH400 carbs do not have the arm extension that the ball or pivot is attachment point that is needed for a TH350 kickdown cable link. TH400 kickdown is electrical and does not need that attachment point.
TH400 trans has vacuum modulator @ front of pan, pass side. TH350 has vacuum modulator @ rear of pan on pass side. Powerglide has vac modulator @ rear of pan on drivers side... |

Pop the hood and look down towards the side of the trans. If you see a modulator, it's a t400. |

Re: carb 7029223
It's likely the original.
No difference in either carb, just the missing part of the lever for a turbo 350 kick down. But, You've got a turbo 400 kick down switch so that part is cut off. Find your carb in here about 1/4 way down the link. http://www.digitalcorvettes.com/foru...ad.php?t=88376 |
